Full Ceramic

The aesthetic demands of the American consumer have been increasing through the years. The NDX Full Ceramic family of crowns can meet this demand. These restorations offer high translucency, natural vitality and excellent marginal integrity.

PearlPress™

PearlPress is a second-generation lithium disilicate crown. PearlPress is made from a lithium disilicate structure that is denser than other similar materials; making it just as versatile in the mouth, but with improved aesthetics and strength. The improved crystalline density also assists with stability allowing NDX to match value much easier.

Seating Recommendations

Bonding: Use self-cure or dual cure adhesive cement for most restorations. For cosmetic veneers, use light cure or dual cure cement with shading options.

Cementation: Indicated for full coverage crowns only. Use self-adhesive resin cement or resin modified glass ionomer (expansion less than .5%) in situations where a conventional cement would normally have been used.

Adjusting & Polishing Recommendations

Use a fine grit diamond bur at a slow speed with copious amounts of water to avoid over-heating the glass-ceramic.

Adjusting and Polishing

Bonding or Cementation

Bonding: Indicated for maximum retention and compressive strength of crowns, veneers, inlays and onlays when tooth preps are primarily supra-gingival and isolation is possible. Use self-cure or dual cure adhesive cements for most restorations. For cosmetic veneers use light cure or dual cure cements with shading options. Recommended adhesive resin cements include:

Variolink II (Ivoclar Vivadent)

RelyX ARC (3M Espe)

Calibra (Dentsply)

Cementation: Indicated for full coverage crowns only. Use self adhesive resin cements or resin modified glass ionomer (expansion less than .5%) in situations where a conventional cement would normally be used, i.e., a retentive prep design, a high-strength restoration with adequate thickness, or a tight fitting crown. Some recommended self-adhesive cements include:
